Latest Patents
One of Seiki Maruta's latest inventions is a brake monitoring device for railroad cars. This device is equipped with a first comparison unit that compares the electrical brake power equivalent signal with a first standard value. It judges whether electrical brake power is generated and closes the locomotive brake deficit check circuit with an interlock relay when the electrical brake power equivalent signal is smaller than the first standard value. Conversely, it opens the locomotive brake deficit check circuit when the signal is larger. Additionally, the device includes a second comparison unit that assesses whether electrical brake power is supplied to the trailer car's brake power. This innovation significantly improves the safety and simplicity of delayed-action control brake devices, especially in scenarios where brake power is not supplied to the trailer car.
